HELP ASAP//BRAINLEST+THANKS: Subj:gravity formula stuff
Y_Kistochka [10]

Answer:

6.46

Step-by-step explanation:

h(t) = (1/2)att^{2} + v0t + h0

Origin is at surface of water (h = 0), up is positive.

a = -g = -9.8 m/s^{2}

v0 = 25 m/s

h0 = 50 m

h(t) = -4.9t2 + 25t + 50

Find t when

7 = -4.9t^{2} + 25t + 50

4.9t^{2} - 25t - 43 = 0

t = [1/(2*4.9)] [25 ±√(25^{2} + 4*4.9*43)]

t = (0.102)(25 ± 38.312)

t > 0 ⇒ use only the positive square root

t = (0.102)(25 + 38.312) ≅ 6.46 s

It is 7m above the water at about 6.46 s
